Generator & Switch Room Applications
National Grid substation, battery energy storage (BESS), hospital generator plant, or heat pump enclosure, we can provide a fully dimensioned NBS-style specification with door thicknesses, louvre free-area calculations, hardware schedule, and fabrication details suitable for manufacture.
For a power station, substation, transformer compound, generator building, or DNO intake room, steel louvre doors are normally specified to provide security, weather protection, ventilation, fire resistance (where required), and compliance with utility standards.
Typical Power Station Louvre Door Specification
Door Type
- Heavy-duty steel louvred personnel door
- Single or double leaf
- Purpose: ventilation of electrical equipment rooms, transformer chambers, switchgear rooms, generator rooms
Door Construction
- 1.5–2.0 mm galvanised steel skins
- Reinforced internal steel frame
- Fully welded construction
- Minimum 50 mm thick leaf
- Polyester powder coated finish
- Standard colour: RAL 6005, 7016, 7035 or utility-specific finis
Ventilation Performance
Typical design criteria:
Room Type Air Velocity Through Louvre Transformer Room 2–3 m/s Generator Room 3–5 m/s Battery Room 1.5–2.5 m/s Switchgear Room 2–3 m/s Free area is calculated from equipment heat rejection.
Example:
- Transformer dissipating 40 kW heat
- Required airflow ≈ 30,000–35,000 m³/hr
- Louvre free area required ≈ 3–4 m²
